Compact, ready-to-mount and easy-to-install, SKF sensorized tapered bearing units form part of the braking system. They optimize frictional engagement of the driving wheels on starting-up, detecting the direction of rotation and bearing temperature.

These units offer the ability to detect:

rotational speed for the wheel slip/slide protection

(WSP or WSSP) and traction control unit (TCU)

bearing temperature signal for the on board monitoring system

direction of movement

positioning for the European Train Control System (ETCS) and the Italian SCMT (Sistema controllo movimentazione treno) automatic train control systems
